TOY AIRSHIP.

.o all whom it may cwwem:

Be it known that I, GUsTAv ENGISCH, a

citizen of the German Empire, residing at Berlin, Prussia, Germany, haveinvented certain new and useful Improvements in Toy Airships, of whichthe following is al -Fi f. 2 is a side view. and I `i u 3 a lan ot thesaine.

The same letters of reference have been used in all the views toindicate correspondiner parts.

l teferring to the drawinga indicates a l buoyant body which ispreterably made of rubber. 'lhe said buoyant body has the usualcigar-like form, and it can be inflated by a suitable gas thespeeitiogravity of which is less than that of the air. -ltrom the` bodya car fm/ and a frame are suspended. At its 'front end the frame b 1sformed with a bore for a propeller shaft c carrying at its end apropeller rl. To the rear end of the frame there is secured a connectingmeans,

for example a hook f. Through the latter and through a hook provided atthe rear end ot' the propeller shaft a rubber band f/ is looped two orthree times. To the rear end ot' the. frame l' a vertical shaft /i islinked which carries a rudder 'i consisting of a frame covered withpaper or fabric. 'lhe shaft is held against rotation by friction, sothat it i'eniains in its position when adjusted for performing a flight.The frame also carries horizontal planes n` which can be turned inbearings of the frame when the air ship is to be raised or lowered. Alsothe planes n are adjusted for each trip of the ship, and they remain intheir adjusted position to the end ol the flight.

The frame b ol the car is secured to the buoyant body by rigidconnecting means. 'l`herefore the earis not suspended within a specialballoon netting. Preferably the said rigid connection consists olone. ormore elas- Specitcation of Letters Patenti.

Application tiledA December 31, 1908. Serial No. 470,185.

Patented Feb. 15, 1910.

ticrods k which are looped in tlielinanner shown in Fig. 1. Thedepending portions of each rod are intersecting each other; at theirpoint of intersection they are interconnected, as indicated with 1 inEig...1. The ends of the rods are secured tothe frame of the car. Byproviding looped iods as described tlie saine rods may be used forballoons of different sizes. .lhe buoyant body.

is pressed into the loop sutliciently to produce a rigid connection ofthe latter vwith the frame. They can be longitudinally shifted on thesaid body. The connectinr rods f, the fraaie b and the car m are relerably inade of very light material, suc i for example as bamboo, sothat the :ir ship is buoyantavithout requiring a balloon of excessivesize.

Instead ot' the driving and steering means' referred to other suitablemeans may be provided.

ln order to drive the air shi the propeller d is rotated aboutl itsaxis, so t iat the rubber cord r/ is put under tension. When the`propeller is released it is rotated in the opposite direction by therubber cord, whereby the air ship is driven.

'lhe air ship is steered by the rudder and the planes fn, which areadjusted before starting the saine. The rudder and the planes are heldin their adjusted positions by friction.

I claim:

l. A free. flying toy air-ship comprising in combination a buoyant body,a. frame, driv.- ing means, steeringr means, and a plurality of rodsattached to said frame, and embracinggr portions of said body. the twohalves of each rod intersecting each other between said body and saidframe.

2. A free flying toy air-ship comprising in combination a buoyant. body,a frame, driving means, steering means, a lurality of rods attached tosaid frame. an( embracing portions of said body, the two halves of eachrod intersecting each other between said body and said frame and beingintercom neeted at their point of intersection.
